What the Law Actually Prohibits

The federal Fair Housing Act makes it unlawful for landlords to discriminate based on seven protected characteristics: race, color, national origin, religion, sex, familial status, and disability. These protections extend to every stage of the rental process — advertising, application, screening, and lease terms.

In practice, this means landlords cannot ask questions that are designed to reveal — or that would disproportionately screen out — applicants based on these characteristics. Common prohibited questions include:

  • "What country are you from?" or "What language do you speak at home?"
  • "Are you married?" or "Do you have children?"
  • "What church or religion do you belong to?"
  • "Do you have a disability or medical condition?"

Beyond federal law, many states extend protections to additional classes. Source of income (including housing vouchers), sexual orientation, gender identity, and marital status are protected in a growing number of jurisdictions.

Exemptions Are Narrower Than Many Assume

The Fair Housing Act contains limited exemptions — most notably for owner-occupied buildings with four or fewer units (sometimes called the 'Mrs. Murphy exemption') and for certain religious organizations. However, these exemptions do not permit discriminatory advertising, and many state laws eliminate them entirely. If you're renting in a small building, don't assume your protections disappear.

What Landlords Are Legally Allowed to Ask

Fair housing law does not prohibit landlords from screening applicants — it prohibits discriminatory screening. Landlords retain wide latitude to evaluate financial reliability and rental history using neutral, non-discriminatory criteria. Lawful questions and requests typically include:

  • Income verification: Landlords may ask for proof of income and apply an income-to-rent ratio (commonly 2.5x to 3x monthly rent), provided it is applied consistently to all applicants.
  • Credit history: Running a credit check is standard practice. Learn more about how this fits into the process in our breakdown of how rental applications actually work.
  • Rental history and references: Landlords may contact previous landlords and ask about your payment record and lease compliance.
  • Criminal background: This area is evolving. HUD guidance discourages blanket bans, and some cities and states restrict when and how criminal history can be used.

The key legal principle is consistent application. A question or policy that is neutral on its face but applied selectively can still constitute discrimination.

Federal protected classes under the Fair Housing Act

Race, color, national origin, religion, sex, familial status, and disability are the seven classes protected under federal law since the Fair Housing Act's 1988 amendments.

Disability Questions: A Closer Look

Disability protections under the Fair Housing Act are among the most detailed. A landlord cannot ask whether you have a disability, request your medical records, or require you to disclose a diagnosis. What they can ask is whether you are able to meet the requirements of the tenancy — such as paying rent on time and complying with lease terms.

If you request a reasonable accommodation or modification (a policy change or physical alteration to accommodate a disability), the landlord may ask for documentation confirming the disability-related need — but only in that specific context, and only when the disability is not obvious. They cannot demand your full medical history or your doctor's treatment notes.

For a detailed look at what accommodations landlords must provide, see our article on renting with a disability.

Keep a Record of Every Question Asked

If a landlord asks you something that feels inappropriate, write it down immediately — including the date, the exact wording, and any witnesses. If you're communicating by email or text, save those messages. A documented record is essential if you later decide to file a fair housing complaint.

If You Suspect a Violation

If a landlord asks you something that seems discriminatory — or if you're denied housing and believe a protected characteristic played a role — you have legal recourse. The U.S. Department of Housing and Urban Development (HUD) accepts fair housing complaints online and by phone. Your state's fair housing agency or a local legal aid organization may also be able to assist.

Document what happened as specifically as possible: the date, what was asked, how you responded, and any written communication. This record strengthens any complaint you file.

It's also worth knowing that landlords have their own disclosure obligations. Our guide on what landlords must disclose before you sign covers the information they are required to share with you before a lease is executed.
